The Upgraded Monster Transmutation System

Time passed by quickly, and one week flew by in the blink of an eye.

Jiang Feng picked up a red-colored Space Crystal Core as his face darkened.

Only now did he realize he had missed one crucial question.

And that was how would he leave this place.

The Efreet had only told them to destroy the blue ice crystals when they entered this place. He had also promised them rewards. But he never said how they could escape from this place under the Yin-Yang Lake.

Only after giving it some more thought did Jiang Feng realize that they were deceived by the Efreet.

After the Efreet got them in, regardless of whether they destroyed the blue ice crystals, they would be sealed within this place. If they wanted to leave, they would need to keep on destroying the blue ice crystals and get the scarlet red Space Crystal Cores and master the Space Tunnel skills.

And the more blue ice crystals they destroyed, the more benefits the Efreet would gain.
